resident of No. 36 Snndweg, l mnbnrg. Germany, hnveinvented certain new and useful improvements in Resilient \iheels, of which the following is o specilicatimi.

The invention relates in a. resilient wheel for vehicles of all kinds, and is broadlv characterized by the 'feet that an exlerno-l wheel member is arranged by means of spokes on at central rigid wheel member, 'the inner and outer ends of the spokes of the outer wheel member being provided with indie rubber cushions, of which the'inne-r cushions are errengcdon bolts in eyes in the rigid wheel member or in thespokes and. the outer cushions in on )5, which may be mad e in two mrts, andqwhici ore rigidlyconneclml with the wheel r-iin. i

Three constructional forms of the novel wheel are illustrated in the accompanying drawing, in which-: 1 Figures 1,3 and 5 are side elevations, aortly in section, of it qua rter of it wheel, Figs. 2, 4 rind 6 represent. sections on the line' A B, Cl), and E-F'of Figs. 1,3 and 5 resp cc-ti'v e ly licotion, .and Fl 's. 8 and 0 are details (at a modification of .t recap. i

The spokes 2' of the inner wheel member the hub 1 and on the other hand with e. crown 3, orthe hub-1, thespokes .2 and the crown 4 0 13. The s o'kee 4 are jointed to t e crown 3 by .3' may form one piece The spokes 4 of the outer wheel mom )era-re jointed to the crown 3 between each pair of spokes 2. Enchof the spokes t is provided-Quits inner end with a fork 5, with wh ch it enge {es the (Frown incense the bolts 6. The bolts 6 are surindie rubber rings 7 which fit rounded by into the ho es inthe crown 3. By this-moons the connect-ion between the spokes 4 and the crown 3 is rendered resilient. .The bolts 6 are secured by bendingover their oil-set ends- 6 which ore formed as e split pin, or in any other suitable monner.

Plates 8 are rigidly connectedto the outer ends otthe spokes. 4, each plate hein sur. rounded by a cap 10 rigidly connected with the wheel rim. 9., and being-provided with two round-pins 8* which ere fitted into the radial grooves 10 of 'the osp 10, in which grooves they are able-to move they form Fig. '7 is n-section ol-at modi- Specification of Lett'ero Patent.

and is held between the plate 8 and a second tween two plates irigidly attached to the hub 1, and to which they are resiliently jointed bymeons of bolts 6 and indie rubber rings. 7 passed around tho-latter, these rin each being composed'ol' a number of was iers of op i'ropriate section if desired.

in the third constructional form of wheel for lighter vehicles which is illustrated in Figs."5 end'fi, the control wheel member consists of two equal disk-shaped ports 3 and 3 which are bolted together bv moons of screw bolts 14; at their ed es tiesc mrts form chambers inwhich t ellettene' ends 5' of the spokes 4 are yieldingly mounted by means of their indin'rubber rings 7 carried by the bolts 69.

In order to facilitate the dismounting of individual spokes 4 the cops 10 which-ere rigidly connected to the wheel rim 9 mey be divided as shown in Figs. 8,8316 9 of the draw- 111 n mbers for the purpose of uniting. them The-lugs 10- provided-on the two cop likewise serve as stiffening lllOS.

Fig. 7 shows it: we of dust and water tight oint between see 10 end the crown 3 of the inner wheel mom yer.

In order to constitute this joint, annular pr0- jeetions .16 and 17 ere-arranged on the caps and on the crown and provided with grooves example it form of 16 end 17 respectivelyfor the reception of fabric covers 18. The ends ofthe covers 18 which are drawn over' the projections 16 and 17 are attached thereto by means of wiresl or in any other appropriate manner.

What- I claim is: A vehicle wheel, wheel-member, spokes pivoted thereto, cush- 7* ions intermediate said member and s okes, an outer wheel-member, caps secured t ereto emeee grooves, pins on the grooves, and cushsfimkes and outer y as specified.
